10 Claims. (61. 16926) NITE The present invention relates particularly to ends of a short bar 29, the said bar being formed that type of fire extinguisher wherein a frangible of two parts connected by a suitable fusible container of fire extinguishing material is shatmaterial at 21 and, of course, holding the memtered by means rendered operative by heat genhere under tension.

3. A breaker device of the character described comprising a member adapted to underlie and support a receptacle for fire extinguishing liquid and having oppositely disposed orifices formed therein, a pair of resilient hammers mounted therein and operative through said orifices, and heat releasable means connecting the hammers to normally hold them in an inoperative position.

4. In combination, a container having a lower discharge end, a frangible receptacle for fire extinguishing material mounted therein, supporting means for the receptacle disposed within the container and having heat responsive breaker means mounted thereon in operative relation to the receptacle, a liquid distributor mounted in the discharge end of the container to support the supporting means for the receptacle and said supporting meansbeing constructed and arranged to pass the released liquid to the distributing means.

5. In combination, a container having a lower discharge end, a frangible receptacle for fire extinguishing material mounted therein, an inverted cup-shaped element mounted in the container to support the receptacle, heat responsive breaker means mounted on said element in operative relation to the receptacle, a distributor member mounted in the discharge end of the container to support said cup-shaped element and said inverted cup-shaped element being constructed and arranged to pass the fire extinguishing material from the receptacle to the distributor. 1 a

7. In combination, a container having a lower discharge end, a frangible'receptacle for fire extinguishing material slidably mounted therein, and apertured element slidably mounted in the container to support the receptacle, heat responsive breaker means mounted on said element in operative relation to the receptacle and normally tending to operate through the apertures, and supporting means for the apertured element detachably mounted in the container said means comprising a distributor plate arranged below said element.

8. In combination, a container having a lower discharge end, a frangible receptacle for fire extinguishing material inserted therein, an apertured element inserted in the container to support the receptacle, heat responsive breaker means mounted on said element in operative relation to the receptacle and normally tending to operate through the apertures, and supporting means for the apertured element detachably inserted in the container, said means comprising a istributor plate arranged below said element.

9. A breaker device of the character described comprising a member adapted to underlie a frangible receptacle for fire extinguishing ma terial and having openings therein, hammers mounted thereon and normally tending tooperate through the openings, and means connected to the free ends of the hammers to normally hold them in an inoperative position.
